[Expression of the kallikreins-kinins system in the corpus cavernosum of rats].

OBJECTIVE: To study the expression of the kallikreins-kinins system in the corpus cavernosum of rats. METHODS: The expression of tissue kallikrein I and kinin B2 receptor gene in the corpus cavernosum and heart of adult rats was detected by reverse transcription polymerase chain reaction (RT-PCR). RESULTS: The tissue kallikrein I and kinin B2 receptor were detected in the corpus cavernosum as well as in the heart of the rats and the contents were similar. CONCLUSION: A kallikreins-kinins system exists in the corpus cavernosum of rats, and the content is rich, almost similar to that in the heart.
